Description

Automatic arc reciprocating motion type computer monitor

Technical field:

The present invention relates to the computer monitor that cervical vertebra and periphery supporting tissue are shielded, specifically relate to a kind of automatic arc reciprocating motion type computer monitor.

Background technology:

Neck is the path of important nerve and blood vessel, but due to the development of modern civilization, the supporting tissue of neck is but more and more fragile, as cervical vertebra, ligament and muscle etc., and neck is often long-time deadlocked when a state, cause especially load uneven, cause the injury of neck; These injuries can cause the retrograde hyperplasia of vertebra to change, and maintain the hyperplasia plumpness of stable large ligament and the weakness of musculi colli, and the above two cause blood vessel and neural compressing, and latter increases the weight of the above two development.Thereby the head of human body deadlock for a long time not, once like this for a long time, must there is above-mentioned pathological state and occur multiple symptom, be exactly clinical alleged cervical spondylopathy.Along with the universal people of computer are more extensive in " deadlock " of neck, people more and more recognize the urgency addressing this problem, notification number is that CN1956642A application for a patent for invention " rotatable, mobile computer monitor and televisor " has just proposed good imagination, attempt to realize and rotate arbitrarily and move with programmed control, with existing technology, also can realize completely, but move modes a lot of described in it are unfavorable for vision health, and because too complicated cost is higher, can not solve at present the problem of popularization and application.All " motive computer display " by name, notification number is CN201091023Y utility model patent and CN101055772A patent application, basic more complicated spiral arm technology, the directions question of even also considering screen wherein having of adopting revised with gear, consider that in addition screen lifts reduction with column automatically, seem more comprehensive, but ignored three fundamental points: 1, as spiral arm is too short, stroke is not enough, if spiral arm lengthens, rear structure is too fat to move, and super large takes up space; 2: from the angle of physiological and pathological, the plate-like rotary moveable of the cone of neck is maximum to disperseing deadlocked POL effect, and the swing angle of existing computer liquid crystal displayer curtain is adjustable, change sitting posture adapts to this adjusting and is also easy to accomplish, so the principal contradiction of cone plate-like rotation is not caught in a lot of designs, simple thing is complicated, because the cause of invention is not to do neck and eye health protection behaviour with computer commander people, but will reach the more reasonably distribution of the load of cone ligament and muscle; 3, reasonable constant sighting distance can keep regulating the state of releiving of lenticular ciliary muscle, thereby keep crystalline lens not occur in continuous adjustment state, and can there is expendable lenticular deformation in prolonged and repeated dynamic adjustments, can not on the automobile travelling, read a book is exactly this reason, and employing spiral arm mode, all can cause screen that constantly front and back dynamic displacement occurs, it is to be against medical science applied to the health-care effect of eyes that this mode of hindering eye hygiene is said to be.

Summary of the invention:

Technical matters to be solved by this invention be computer monitor can be low-cost and low energy consumption realize regular automated movement, and meet medical health care.

The technical scheme that the present invention addresses the above problem is:

A kind of automatic arc reciprocating motion type computer monitor, comprise display screen main body, display bracket and chassis, is characterized in that by universal wheel, being supported under described chassis, stand on a horizonal base plate, on this base plate, have arc track outstanding prop up in the track support of base plate both sides on vertical with base plate.Below display screen, Mian Shang both sides, display chassis are provided with rail wheel support, and this support is provided with the support wheel that axle is vertical with arc track; The reducing motor that display bracket is provided with, its output terminal is provided with active friction wheel, and this is taken turns with above-mentioned support wheel and is clamped on arc track; And whole display can follow this track translation when reducing motor starts.The rear portion that is positioned at base is provided with commutation gauge tap, this switch knob is shaft-like sensing computer parallel with base plate dead astern, while moving to one end of track along track under the driving of computer at motor, be equivalent on the base plate of this position, the handle of commutation gauge tap can contact the limited post of being located at base plate both sides, motor reversal and realize computer monitor and move back and forth.The track of described arc track is one section and take and meet medical science applied sighting distance as radius, the arc that the two order line mid points of take are the center of circle, this arc is symmetrical with respect to computer operator, and arc pushes up display screen dorsad, and arc length is when being enough to cause the Small-angle Rotation of computer operator's neck; This display screen slowly the mobile head that drives computer operator unconsciously in corresponding movement.

The utility model has following outstanding advantage and remarkable result compared with prior art:

1, computer popularity rate is very high, and total amount is quite large, and the design of the unreasonable increasing energy consumption in any point all can cause total energy consumption to occur huge numeral.Energy-saving and emission-reduction not only will be embodied in daily life, more will be embodied in the design of new product.The utility model technique scheme adopts standing of chassis to the wheel rolling friction of carrying, to remove that power more or less that prior art exists is refused load condition and structure is simple and clear, obviously greatly reduces energy consumption.

2, the utility model changes traditional display and on support, moves as the moving horizontally of the full carrying of bearing, and operation more steadily and reduce noise.

3, the prior art exemplifying is attempted face mask and is arrived, but actual be to have too much of a good thing.From medical science applied angle analysis, it is actual that on human body maximum, injury is that before neck back of the body waist, spy state causes huge power to refuse load to the damage of nape waist and lower the closer impact of screen height focusing on eyesight of this posture, and actual universal liquid crystal display all has front and back manual steering function, as coordinate sitting posture, be easy to accomplish standing to support of back neck, and under this situation, stand to the deadlock key of problem on the contrary, so the deadlocked harm of neck when the utility model has been removed use computer with low cost, meets eye hygiene simultaneously.
